What do you want to use the string for? If you want to print it (to stdout or to file), just print it. It is a pointer to a NULL terminated character array (LPTSTR = Long Pointer To STRing, the 'Long' is a relic of the old 16 bit days), use it like you would any other.

Sorry, I saw you were interested in a string and looked at the string in the function definition. Why not try to print the string? You do realize, don't you, that the MS_DOS volume is being printed in hex?
